NUTRITION - Essay Example During this time the lifespan of an individual could stretch to hundreds of years, according to science and history. The same fact conforms with the current reality, which shows a systematic reduction in the lifespan of individuals over the time. This reduction in lifespan has also corresponded on increasing shift from fresh vegetables to high-content proteins and junk food. The logical conclusion is that the increasing dependency of man on non-vegetarian foods is the one major cause of reduced span of living in the current civilizations. Fruits and vegetables fall under the food category of vitamins. The main purpose of vitamins is to protect the body. They build the body defenses by providing the immune system with the necessary nutritional support (Beezhold, Bonnie, Carol Johnston and Deanna 14). A consistent reliance by an individual on this kind of support will naturally produce positive results in terms of longevity and good health. In my opinion, the logic behind the long spans of life for the vegetarians revolves around the elimination of diseases from the body. Diseases have an attrition effect to the body. A person who does not consume fruits and vegetables regularly is more susceptible to diseases. On this account, it follows that the more a person, an individual, or a group relies on fruits and vegetables, the more they are likely to lead healthier lives. Vegetarians fall within this category. Fruits and vegetables are known to be oxidants. They eliminate poisonous substances from the body leaving it free from disease-causing pathogens. The natural defense bodies require consistent external support in order to provide the necessary support for the body. In this perspective, it becomes important to consider vitamins in terms of their capacity to shield the body from harmful substances that are resident in the various places, which meet the body. As such vegetarians have their body systems maintained at the highest levels in ways that protect them

Research Anaylsis - Essay Example The â€Å"No Child Left Behind Policy in the United States viewed the teachers as dutiful mechanism to foster that so called proven literacy education programs and methods. This follows the â€Å"Do as I do, not as I say† rule. This method implies that students are more likely to perform well and engaged themselves in any activities especially in reading and writing when they learn from teachers who manifest the same traits. Therefore, the competency of teachers being active readers and writers influence the performance of the students. It brings life to the classroom and affects the students interest and enthusiasm to participate in reading and writing and be effective readers and writers themselves. On the contrary these studies can just be a generalization of the whole scenario. The focus of this analysis is the individual experience and approach of an effective teacher. Individual teacher has different attitude, beliefs and practices. Therefore, the teachers individual capacity will affect their performance in sustaining and delivering effective literacy instruction and learning opportunities to students. This is an individual role for them as educators. As a support to this, Susi (1984) found that teachers assumed different positive writer roles and identities as a result of their participation in writers workshops. They experienced the struggles and joys of composing and revising, which, in turn, not only taught them to be more empathetic to the experiences of their students, hut also "humanized" them to their students. Therefore, the extent of what the teachers would facilitate to their students could be determined by their own experiences. It is absolutely hard to teach something when in fact, a person does not have enough knowledge regarding that subject matter. This is further supported by the report of some other researchers stating that more diverse teacher self-concepts as writers from

Impact Of Climate Change On Arctic Ice Environmental Sciences Essay

Impact Of Climate Change On Arctic Ice Environmental Sciences Essay Climate change concerns to a statistically momentous deviation in either the mean state of the climate or in its variability, remaining for an extensive period (normally decades or longer) (What is climate change, 2001). Climate change is term that adverts to any major and long-term change in average weather in a specified region or whole Earth. Fundamentally important variability of average weather over longer time period can be depicted as climate change. Climate change is due to natural internal procedures or external pressures, or to relentless anthropogenic alterations in the composition of the atmosphere or in land utilization. Earlier in the beginnings of earths history climate changes were normally induced by different vibrant processes on earth but recently it is caused by human activities. This is the reason that in our everyday talks the term climate change refers to climate change caused by global warming. The most disposed signs of climate change are Arctic Sea Ice. Arctic Sea Ice is declining at rapid level which shows that change has already began. This time, climate change is only due to the recent human activities and had resulted in various negative outcomes. From last two centuries, the worlds global mean temperature has amplified by 0.6Â °C (1Â °F) and it appears that the present trend goes beyond the natural climate variance. Due to this increased warming, the average temperatures of Arctic region have mounted almost twice as fast as in the rest of the world and in this region climate changes are being felt extremely (Eilperin Sheridan, 2009). This warming in the region can be attributed to the present human activities that are directing towards climate change. With the effect of the climate change, the Arctic sea ice cover is continually shrinking and becoming thinner and the region is warming more rapidly than scientists had anticipated. This is only due to the increased amount of carbon dioxide (CO2) in the atmosphere. The amount of carbon dioxide has increased by 35% since the industrial revolution and it is mostly due to human activities like burning of fossil fuels and the clearing of land. In addition to this, extending greenhouse gas releases are also causing momentous change in climatic conditions, which in turn is affecting the Arctic sea ice. This impact of climate change on the Arctic Sea Ice is making numerous negative effects on wildlife like polar bears and augmenting erosion of coastlines in Alaska and Siberia. Arctic sea ice loss is also resulting in the changes in atmospheric patterns that are causing condensed rainfall in the American West or amplified precipitation over western and southern Europe. If this situation of climate change is not managed, the decline in Arctic sea ice could also affect the whole world. Discussion Significance Scope of the Issue The management of the issue of climate change and its impact on Arctic Sea Ice is essential as it could profoundly influence Arctic ecosystems, global climate and flow of oceans and atmosphere in the north. Sea ice impacts coastal areas in countless ways. Bottom ice in trivial water acts with sub-sea permafrost, which in turn controls erosion and sediment transport. The existence of sea ice precludes waves from eroding coastlines (Eilperin Sheridan, 2009). The features of near-shore ice are critical in numerous respects and need to be prevented as soon as possible as otherwise it could direct in drastic results related with coastal area. In addition to the impact on coastal areas, the Arctic sea ice also plays a prominent role in Arctic ecology, most noticeably for the numerous fish, bird and mammal species that live in, on, or beneath sea ice, or are otherwise inhibited or supported by its existence. The present altering sea ice conditions will not only make an impact on the marine ecosystem, but also it will have complications for terrestrial surroundings and the wildlife and people settled there (Sea Ice: Implications of changes in arctic sea ice, 2001). Sea ice shelters the fundamental water column and blocks sunlight that in turns affects the productivity of the Arctic Ocean that is impelled by plankton and algae. With the sea ice changes all these sea related aspects are facing disruption. Ice-associated species had also started conferring radical changes and destructions (Scientific Facts on Arctic Climate Change, 2009). Inquiring these and other such alterations and their significances is decisive to comprehend the full role of sea ice in arctic ecology. With the changes in sea ice, humans living in the Arctic region are also affected in numerous ways. Marine mammal hunters necessitate access to prey, which depends on the distribution, quality and movement of the ice fields. All these aspects impact the capability of the hunters to arrive at and carefully recover the animals that are gleaned (Sea Ice: Implications of changes in arctic sea ice, 2001). Changes in ice distribution may influence both access and scheduling of harvest, potentially conflicting with other seasonal activities. Specific Causes of Change in Arctic Sea Ice The specific causes of change in the Arctic Sea Ice are global warming, atmospheric changes and greenhouse releases. With the ever increasing release of greenhouse gases prominent changes has occurred in atmosphere, which in turn had increased the temperature. All these aspects are causing global warming, which directly or indirectly makes an effect on Arctic sea ice. On the whole it could be said that the most important reason of this change in Arctic sea ice is due to the climate change, which in turn is the result of following factors: The most prominent reason of climate change is releasing of greenhouse gases and aerosols into the atmosphere. From last two hundred and fifty years, the concentrations of greenhouse gases and carbon dioxide have increased due to the burning of fossil fuels for energy production (Climate Change, n.d.). Another prominent reason of climate change and atmosphere change is deforestation, which is related with agriculture and urban development and harvesting timber for fuel, construction and paper (What causes global climate change, 2005). Sulphate Aerosols and Black Carbon are other two crucial instances of anthropogenic forcings. Current industrial activities have recently increased the concentration of sulphate aerosols and black carbon in the atmosphere that is making imperative effect on our climate in the form of drastic weather events and reduction in Arctic sea ice. Critical Analysis Evaluation of Environmental and Ecological Consequences Climate change and its effects on the Arctic sea ice is the most serious environmental issue in present as it is frightening the world environment and Arctic ecology. Average annual temperatures in the Arctic region have altered greatly in comparison to the increase in global average temperatures. With the impact of global warming, effects like higher temperatures rise in sea-level, melting of sea ice and glaciers, augmented precipitation in some regions and drought in others are become very common (Arctic Sea Ice Decline May Trigger Climate Change Cascade, 2007). With this global warming and climate change, the Arctic region is warming at an alarming rate and this had a distressing affect on Arctic ecosystems, admitting sea ice, permafrost, forests and tundra. Melting sea ice is affecting populations of marine mammals, caribou, polar bears and the continuation livelihoods of people, which in turn is creating an imbalance among the ecological system (Scientific Facts on Arctic Climate Change, 2009). With these changes in sea ice, a number of wildlife populations of Arctic region are forced to adapt to changes in their habitats. Thawing permafrost the result of sea ice changes has damaged houses, roads, airports and pipelines and is inducing landscape erosion, slope unsteadiness and landslides. All these environmental consequences are becoming unmanageable. The important features of Arctic environment like forest and tundra ecosystem had started damaging due to this impact of climate change (Effects of Climate Change Today, 2010). This in turn is resulting into forest disturbance, insect outbreaks, blow down and fire. Climate warming Climate warming and insect infestations are making forests more susceptible to forest fire. On the whole, it could be said that changes in Arctic sea ice is causing significant environmental and ecological consequences. Success of Solutions Proposed Applied Climate change is affecting the whole world and prominently the Arctic sea ice. Number of developed and developing countries are working together to discover the solution of environmental challenge of climate change. From the time, this issues has emerged a number of efforts had been done some of which had attained success and some had failed. In June 1992, 154 countries signed the United Nations Framework Convention on Climate Change (UNFCC) that corresponded to alleviate the amount of greenhouse gases in the atmosphere at levels that would not cause destruction and further consequences. In Kyoto, in December 1997, Japan, Canada and 160 other industrialized nations committed to cut down their greenhouse gas emissions, as component of an international agreement on climate change identified as the Kyoto Protocol. This eventually came into force throughout 2005 (Climate Change, n.d.). In addition to this another environmental agreement, World Heritage Convention is also made in this regard. Till the time these efforts had not attained immense success but with these efforts modest emission reductions had been encountered from industrialised countries. Countries are trying to reduce their emissions as now they had become aware with its severe results and further consequences that are resulting in decrease in Arctic sea ice. Conclusions With this detailed discussion, it could be said that sea ice is a key constituent of the Arctic environment. Directly or indirectly it is striking many of the oceanographic, climatic, ecological and human patterns that portray the region. Changes in sea ice need to be controlled as otherwise it could have significant negative implications for all the above discussed systems. For maintaining present situation, it is essential that all of us become aware with the future consequences of climate change as without this it is not possible to reduce the processes through which climate change is occurring actually. With the understanding of its environmental and ecological consequences it could be said that it is the most severe environmental issue in present.

Salems Lot and The Shining :: essays research papers

Stephen King sets up the perfect horror scene in room 217 by buliding off of Hitchcock and hos own previous work, Salem's Lot. King uses Hitchcock's definition of great horror to set for the scene in romm 217. He also uses background from his old work, Salems Lot. Alfred Hitchcock's idea of horror involves human suspense and teh realistic aspect of scary situations. Hitchcocks masterful directing leads the audience to be the frist to understand what is going on. The characters are left in the dark until the suspense reaches its climax. As the impending danger builds, the viewer is allowed to wtiness the situation before the character. This raises the level of suspense making it more realistic. Hitchcock takes normal situations and adds a terffiying twist. The twist is always something that has never happened, but is definetely possible. Hitchcocks The Birds is an excellent example of this. He takes normal situation with normal birds and turns them into killers. As the birds gather behind one unsuspecting victim, only the audience is allowed to see the impending danger. The woman is calm and collected as she waits on the bench. Hitchcock adds a little scare music and the woman suddenly realizes she is being watched. She whips around in horror a nd the birds are there ready to attack. This scfene is not a common occurance, but to an overactive imagination it could become a very real possibility. Kings early work Salems Lot helps to prove he has created the perfect horror scene in room 217. Salems lot was, at that time, a suspenseful story about vampires and things that lurk in the night. The plot was predictable, new guys come to town, vampires attack, suspcicious old man is accused. When King wrote Salems Lot his techniques for horror and suspense were still yound and under developed. The element of surprise was more evident than that of suspense. The writing of King matured greatly before he wrote The Shining. The scene in roo, 217 us a perfect horror scene as it takes a realistic situation and turns it frightening. As the beginning of the nover danny is warned by Hallorann not to enter room 217. The first step has been completed, the warning. The second step of building the action begins. Danny steals the passkey, but not only that as Jack has been having hallucinations along with Danny.

A Father’s Story

Stories often have a main character that is centered on because he/she fails at some responsibility of theirs or falls short of their goal. In â€Å"A Father's Story† written by Andre Dubus, Luke Ripley is a character that succeeds in his responsibilities as a father. Luke shows love, compassion and above all a protective instinct and desire to help his daughter. He emphasizes that he is very religious although perhaps not very devout. All of these characteristics help him fulfill his fatherly duties to his daughter during her stay at his house. Luke has had an interesting life preceding the main events of the story. He has lost his entire family, making him alone in a large house with nothing but horses and a radio to keep him company. Despite those trials, Luke has it inside him to continually show love to his family when they do return, especially to his daughter even though she kills a man. Andre Dubus emphasizes this love and compassion Luke has through some of the background information he gives leading up to the main events of the story. Dubus shows small details that Luke a centers his attention on and the efforts that Luke puts forth to try and love his family after they leave him. There also comes a point in the story where Luke's heart's â€Å"longing to love† as he calls it, makes him bitter with Father Paul. Luke's friendship with Father Paul brings about another very interesting character trait in Luke. This is his religious side. Based on the way that Luke recounts the events of his life, religion is a mayor part and focus of his life. He seems not to be very devout and strict; he says that â€Å"being a real Catholic is too hard. † Still though, he goes to each Sunday Mass and Father Paul is his best, and in truth his only friend. Luke wakes up early each morning and rides his horse to the church. Luke falters only twice as far as his chastity and marriage beliefs are concerned and he describes those two incidents as having been in the distant past and not a reoccurring habit. Luke also realizes that he cannot force or tell his children what to believe but he still tries to point them in the direction that he believes to be right. Luke explains that his religion and Father Paul help to keep him company and keep him strong when his family left him. The main focus of this story however is not about Luke's love and compassion, or his religion; it is about just his fatherly instinct and desire to protect and help his daughter. The entire story, up till the climax Top point, is aimed at Luke's ability to empathize with his daughter and provide her with the comfort and help that she needs. First of all, Jennifer is the youngest child, the baby in the family. This automatically puts her in the position to receive more attention and care from her father. Jennifer also seems to be the one that visits her father the most often and for the longest periods of time. Luke enjoys the time that he gets to spend with his daughter. He relishes in the little details and subtle changes that take place over time. He points out how they are growing up and getting steadily more mature. Luke shows us that he understands and empathizes with his daughter and her transformation into a young adult when he says, â€Å"it was womanhood they were entering, the deep forest of it, and no matter how many women and men too are saying these days that there is little difference between us, the truth is that men find their way into that forest only on clearly marked trails, while women move about in it like birds. Jennifer then wakes her father in the middle of the night to tell him that she has just hit a man, and might have killed him. This is enough to test any father's love, patience, and temper. But Luke rises to the occasion and his character doesn't falter he firsts comforts his daughter and learns the whole story of what has taken place and what has upset her so badly. Then after she has calmed down, and only after she has calmed down, Luke leaves to try and find this man. The result is that Luke finds the man, and watches him die because he is powerless to save him at this point, he does not tell his daughter this, he only says that the man is dead. Then Luke says something interesting, he tells us â€Å"If one of my sons had come to me that night, I would have phoned the police and told them to meet us with an ambulance at the top of the hill I could bear the pain of watching and knowing my sons' pain but never my daughter's. This illustrates with perfect clarity Luke's special love for his daughter and desire to protect her in a way that varies greatly from that of his feelings for his sons. Stories often have a main character that is centered on because he/she fails at some responsibility of theirs or falls short of their goal. In â€Å"A Father's Story† written by Andre Dubus, Luke Ripley is a character that succeeds in his responsibilities as a father.

Wal-Mart’s Unfair Labor Practices in “Down and Out in Discount America

In â€Å"Down and Out in Discount America,† writer Liza Featherstone (2004) exposes the dirty tactics and unfair business practices that fuel Wal-Mart’s success as a giant retail company, and suggests effective strategies to defeat corporate crime. According to Featherstone, Wal-Mart is one company that literally profits and grows from the presence and worsening of poverty situations, as shown by the results of a study conducted by economist Andrew Franklin which revealed that â€Å"Wal-Mart operated primarily in poor and working-class communities.†Most of the retail company’s customers are â€Å"overwhelmingly female, and struggling to make ends meet. † Featherstone argues that Wal-Mart ensures that its market in the low income segment continually expands by â€Å"creating more bad jobs worldwide. † She also points out that Wal-Mart routinely employs illegal and unethical business practices to maintain its competitive edge over other compani es, including violating wage and labor laws that deprive workers of their living wage and health benefits.More importantly, this set-up â€Å"contribute to an economy in which, increasingly, workers can only afford to shop at Wal-Mart. † The biggest brunt falls on Wal-Mart’s overwhelmingly female workers. As a result, the company has been the subject of â€Å"the largest civil rights class-action suit in history† which â€Å"charges the company with systematically discriminating against women in pay and promotions.† The company has also been cleverly using public funds to subsidize its low wages by encouraging its workers to apply for welfare assistance. Despite the company’s glaring offenses, however, poor women continue to patronize Wal-Mart because it is all they can afford. Featherstone therefore contends that the success of a concerted action against the giant company lies in the ability of stakeholders such as labor unions to go beyond the co nsumer mentality, constructed by big business, in creating avenues of resistance.The author notes that â€Å"to effectively battle corporate criminals like Wal-Mart, the public must be engaged as citizens, not merely as shoppers,† in order to form a movement with enough social and political power to challenge Wal-Mart and to advance the interest of the poor and the working class. Arguably, Featherstone’s article is one of the most convincing and informative pieces there is that provides a balanced and level-headed discussion of an issue that is as inflammatory as â€Å"the â€Å"Wal-Martization† of American jobs.†Ã¢â‚¬Å"Down and Out in Discount America† is clearly intended for a wide spectrum of audience. Featherstone assumes that her readers know Wal-mart but they do not know about its unfair practices and illegal activities. Through the clever use of rhetoric and data, the author delivers an essay that is both incisive and engaging. Featherstone u ses both academic data and well-placed personal narratives of the workers of Wal-Mart to build her case.In the process, she does not need to explicitly state that Wal-mart profits from injustice and deepening income divide, this is already substantiated by the real-life cases and hard statistics that speak about the way the company â€Å"profits not only on women's drudgery but also on their joy, creativity and genuine care for the customer† and conditions its consumers to be heavily dependent on the â€Å"relief† brought by Wal-Mart discounted prices. It is interesting to note that Featherstone incorporates contrary ideas into her piece—such as the welcoming attitude towards Wal-Mart held by poor women—to illuminate and strengthen her stance.Thus, Featherstone avoids taking the â€Å"boycott† stance that would have been too simplistic an answer to as big a problem as Wal-Mart. â€Å"Down and Out in Discount America† also does not have the d epressing tone that most articles dealing with serious social issues are often infected with; this is not to say that the article does not evoke an emotional response from the reader but that it presents an image of women workers, who, despite their desperation and sad circumstance, manage to lend their anecdotes to show the multi-dimensionality of the Wal-Mart experience. One therefore finds it hard not to take Featherstone’s side against Wal-mart.The writer undoubtedly presents a well-informed case that explores the Wal-Mart’s labor issues in both a personal and social angle, and attempts to convince the audience on the logic and soundness of why the poor should stop shopping at Wal-Mart (which Featherstone has already conceded is an exercise in futility) but on why there should be more stringent policies to safeguard the poor from unfair labor practices and why there should be adequate legal measures to punish corporate criminal activities that prey upon the despera tion of the poor and the working class.Featherstone is also right in pointing out the need for a political and social movement that would leverage the interest of the poor and the working class above corporate interests. This movement must be a powerful enough presence to generate political pressure on the government and on big businesses to fulfill their social obligations.Clearly, â€Å"Down and Out in Discount America† is a searing portrayal of what happens when citizens literally put their souls out for a â€Å"bargain† with big businesses, which has transformed them into mere consumers whose participation in political and social decision-making is limited to individualistic shopping and purchase decisions. Fortunately, writers like Featherstone are there to remind consumers that they are, first and foremost, citizens and workers with stakes not only in payday discount sales but in the future and direction of labor and living conditions in the community and the cou ntry.
